Subject: [PATCH] Add ChisFlash MBC5 MAX flash cart profiles

Two configurations for the 32 MiB ChisFlash MBC5 MAX, one per flash chip it
ships with. Both were provided by GBMake, who sell the cartridge, and are
included here unmodified.

- 28EW256A, flash ID 89 89 7E 7E
- S29GL256N, flash ID 01 01 7E 7E
